Tahini is made from sesame seeds that are soaked in water and then crushed to separate the bran from the kernels. The crushed seeds are soaked in salt water, causing the bran to sink. The floating kernels are skimmed off the surface, toasted, and ground to produce an oily paste.
Because of tahini’s high oil content, many manufacturers recommend refrigeration to prevent spoilage. This is particularly true among makers of raw, organic tahini, who will often prepare their tahini at low temperatures and ship and store it in refrigerated cases to maximize quality and shelf life.
Used in middle eastern cooking, it has a peanut buttery flavour. You will find it used in hummus and other Middle Eastern dips.
